STEAM-ENGINE.

Application filed July 14,

To all whom it may concern:

Be it known that I, ELMEI: J. HAMILTON, a citizen of the United States,residing at Indiana Harbor, county of Lake, and State of Indiana, haveinvented certain new and useful Improvements in Steam-Engines, of whichthe following is a specification.

My invention relates to steam or other fluid pressure engines and hasfor its object the production of such an engine of improved constructionand operation.

l/Vith these objects in view my invention consists in the novelconstruction and arrangement of parts which will be hereinafter fullydescribed and more particularly pointed out in the appended claim.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification and in which,

Figure 1 is a plan view of my improved steam engine in its preferredform, Fig. 2 is a side elevation thereof, Fig. 3 is an end elevation,Fig. 4 is a detail side elevation showing the movement of the intake andexhaust pipe connections, and Fig. 5 is an end view of the engineshowing said connections.

Referring now to the drawings 1 designates the engine base and 2 thereciprocatory cylinder mounted thereon. The base 1 is provided with ways3 adapted to fit grooves 4 of the cylinder base 5 and to guide saidcylinder in its reciprocat-ory movement. Sockets 6 are provided on eachside of the cylinder 2 to receive trunnions 7 which are securely pressedtherein. The crank shaft 8 is suitably journaled in suitable standardson the engine base 1 and connecting rods 9 connect the crank pins 10With the trunnions 7 an ordinary piston rod 11 and connecting rod 12being provided.

A cylindrical steam chest 13 is formed integral with the cylinder 2, thesame being preferably provided with rotary intake and exhaust valves(not shown). The valve shaft 14 journaled in the steam chest 13 in axialalinement therewith is provided with a depending rocker arm 15, thelatter being actuated by the eccentric rod 16 which is reciprocated bymeans of an eccentric provided on the crank shaft 8 adjacent a crank pin10. The L-connection 18 is arranged Specification of Letters Patent.

above the steam chest 13 as shown, and is in open communication withsaid steam chest.

Stationary supply and exhaust pipes 19 and 20 are provided and in orderto connect the engine cylinder with said supply and exhaust pipes Iconnect pipes 21 and 22 with the supply and exhaust pipes of saidcylinder by means of swiveled joints 25 and 26 respectively which securesaid pipes 21 and 22 at substantially right angles to said cylindersupply and exhaust pipes. At their upper ends pipes 21 and 22areconnected with pipes 23 and 24 by means of swiveled joints 27 and 28which connect said pipes 23 and 2st at substantially right angles topipes 21 and 22. Pipes 23 and 24L are in turn swiveled to stationaryexhaust pipes 19 and 20 by means of swiveled joints 29 and 30respectively. By this construction steam may be supplied and exhaustedto and from the engine cylinder while the same is in motion and withoutemploying sliding joints.

From the foregoing description it is clear that the cylinder is free toreciprocate and that the steam may be readily admitted to and exhaustedfrom the same through the intake and exhaust pipes respectively.

It will be noted that the crank is so formed that the cylinder andpiston will always move in opposite directions, thus producing a wellbalanced engine.

Various slight changes might be made in the general form and arrangementof parts described Without departing from my invention, and hence I donot restrict myself to the precise details set forth, but considermyself at liberty to make such changes an alterations as fairly fallwithin the spirit and scope of the appended claim.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

In a steam engine, the combination of a base; a cylinder mounted toreciprocate on straight horizontal guides on said base; a piston mountedto reciprocate in said cylinder; a crank shaft; an operative connectionbetween said cylinder and said piston and said crank shaft; stationaryand substantially horizontal supply and exhaust pipes located above saidcylinder; horidoc zontal disposed connecting pipes swiiieletl tiiins' ofsm'id ej 'linder, siib'sta'n'tilly is de- 10 to said supply and exhslustpipes at sub scribed stantially right q gles the eto; vertically Intestinpny whereof I have signed my disposed connecting pipes swivle'clt6 said name t6 this speific'atib'n in the presence of first mentionedconnecting pipes and adapt= two subscribing Witnesses.
